+`mimx95_cm7` and `mimx95_cm7_mx25um` debug the i.MX95 Cortex-M7 while the System Manager keeps running
+on the Cortex-M33; `mimx95_cm33` and `mimx95_cm33_mx25um` debug the Cortex-M33 itself. The Cortex-M33 runs the
+System Manager: a `mimx95_cm33_mx25um` flash halts it and the Cortex-M7, loads the flash algorithm over System
+Manager code and ends with a SoC reset, so Linux reboots; use the cm7 targets to flash without a reboot. Unit tests must not see a probe: `test/unit/test_semihosting.py` opens the first probe
+it finds and halts the cores of whatever board is attached, so run the unit tests with every probe user

+no other file; add any new one to the exclusions.
